Zechariah 14:1-5 (DRB) Behold the days of the Lord shall come, and thy spoils shall be divided in the midst of thee. 2 And I will gather all nations to Jerusalem to battle, and the city shall be taken, and the houses shall be rifled, and the women shall be defiled: and half of the city shall go forth into captivity, and the rest of the people shall not be taken away out of the city. 3 Then the Lord shall go forth, and shall fight against those nations, as when he fought in the day of battle. 4 And his feet shall stand in that day upon the mount of Olives, which is over against Jerusalem toward the east: and the mount of Olives shall be divided in the midst thereof to the east, and to the west with a very great opening, and half of the mountain shall be separated to the north, and half thereof to the south. 5 And you shall flee to the valley of those mountains, for the valley of the mountains shall be joined even to the next, and you shall flee as you fled from the face of the earthquake in the days of Ozias king of Juda: and the Lord my God shall come, and all the saints with him.
Acts 1:1-12 (DRB) The former treatise I made, O Theophilus, of all things which Jesus began to do and to teach, 2 Until the day on which, giving commandments by the Holy Ghost to the apostles whom he had chosen, he was taken up. 3 To whom also he shewed himself alive after his passion, by many proofs, for forty days appearing to them, and speaking of the kingdom of God.
4 And eating together with them, he commanded them, that they should not depart from Jerusalem, but should wait for the promise of the Father, which you have heard (saith he) by my mouth. 5 For John indeed baptized with water, but you shall be baptized with the Holy Ghost, not many days hence. 6 They therefore who were come together, asked him, saying: Lord, wilt thou at this time restore again the kingdom to Israel? 7 But he said to them: It is not for you to know the times or moments, which the Father hath put in his own power: 8 But you shall receive the power of the Holy Ghost coming upon you, and you shall be witnesses unto me in Jerusalem, and in all Judea, and Samaria, and even to the uttermost part of the earth.
9 And when he had said these things, while they looked on, he was raised up: and a cloud received him out of their sight. 10 And while they were beholding him going up to heaven, behold two men stood by them in white garments. 11 Who also said: Ye men of Galilee, why stand you looking up to heaven? This Jesus who is taken up from you into heaven, shall so come, as you have seen him going into heaven.
12 Then they returned to Jerusalem from the mount that is called Olivet, which is nigh Jerusalem, within a sabbath day's journey.
Question
According to those who reject the deity of Christ (that He is "the LORD"), are these two passages speaking of two separate Lords?
(EDIT: Since it doesn't seem to be clear: both mention a Lord returning to, or landing upon at least, the mount of Olives, probably an apocalyptic or end times event; that's the perceived connection. If Jesus is Yahweh, both refer to the same Lord. If not—well, that's the whole question.)
